Diffuser Sheet
Translucent panels that spread light evenly from fluorescent tubes and LEDs, cutting glare while keeping light output high.
About Diffuser
Frosted acrylic is a great product for light control in skylights, windows and light fittings. Egg crate diffuser is a light and versatile product in a grid style with many uses.
Diffuser sheet scatters incoming light to produce even, comfortable illumination, either through a surface texture or through light scattering particles in the material. Opal is uniformly translucent, giving soft, even light and hiding individual LED points, which makes it the standard for backlit signage. Frosted and satin sheet gives a lighter diffusion while keeping some visibility through the panel.
We cut diffuser sheet to exact dimensions for any light fitting. Measure your existing panel or the fitting opening, send us the dimensions, and we will have your replacements ready to install.

The honest picture
Every material has trade offs. Here is where Diffuser shines and where it falls short.
Pros
Replacing yellowed panels is one of the cheapest ways to lift light levels
Opal conceals LED dots for smooth, even illumination
We cut to any fitting size, so retrofits are straightforward
Limitations
Older polystyrene covers yellow over time and need replacing
Not a structural panel, it is a light control product
Diffuser versus the alternatives
Opal versus frosted
Opal gives soft, uniform light and hides individual LED points, which makes it the standard for backlit signage. Frosted or satin sheet gives a lighter diffusion while keeping some visibility through the panel.
Clear acrylic
Clear acrylic transmits the most light but does nothing to control glare or hide the light source. Diffuser sheet scatters the light for comfortable illumination.
